BACKGROUND OF INVENTION

1. Field of Invention

The present invention relates to a bow and arrow and, more particularly,to a bow and arrow set with which an archer can practice arching withoutactually shooting an arrow away from a bow.

2. Related Prior Art

Arching requires extreme concentration, skills in using wrists and arms,and stability of feet. It is an excellent sport for training a person'sbody and mind. This is evidenced by the inclusion of arching in theOlympic Games.

In arching, a body of an arrow is located against a bow. A butt of thearrow is located against a string tied to the bow. The butt of the arrowis moved against the string. Thus, the string is loaded. The arrow isshot by the string on releasing of the butt. Later, a goal is hit withthe arrow. A score can be read from the goal.

However, arching requires a large space to provide an adequate distancefor the travel of the arrow and to protect bystanders. Hence, archingcan only be conducted in certain places, and only a few people arewilling to learn arching.

Therefore, the present invention is intended to obviate or at leastalleviate the problems encountered in prior art.

DEBUTED DESCRIPTION OF EMBODIMENTS

Referring to FIGS. 1 to 4, there is shown a bow-and-arrow set 100according to a first embodiment of the present invention. Thebow-and-arrow set 100 includes a bow 10, a buffer 20, a string 30 and anarrow 40. The buffer 20 is attached to the bow 10. The string 30 is tiedto the bow 10. The arrow 40 is movably connected to the bow 10.

The bow 10 includes a handle 11, two limbs 12 and a pipe 13. The handle11 is located between the limbs 12. The limbs 12 are made of an elasticmaterial. An end of each of the limbs 12 is secured to an end of thehandle 11. The pipe 13 is inserted through an aperture 111 defined inthe handle 11. The pipe 13 is secured to the handle 11. The pipe 13includes a channel 131 defined therein, a vent 132 at a first end of thechannel 131, and an aperture 133 at a second end of the channel 131opposite to the first end. The diameter of the channel 131 is largerthan that of the vent 132. The diameter of the channel 131 is largerthan that of the aperture 133.

The buffer 20 is located within the channel 131, near the vent 132. Thediameter of the buffer 20 is larger than that of the vent 132. Hence,the buffer 20 cannot be removed from the channel 131 via the vent 132.The diameter of the buffer 20 is smaller than that of the channel 131,leaving a first gap between the buffer 20 and an internal side of thepipe 13. The first gap is in communication with the vent 132. The buffer20 can be a block of an elastic material such as rubber and silicone.Alternatively, the buffer 20 can be a device such as a compressionspring, an air bag and a pneumatic or hydraulic cylinder. The buffer 20is a block of rubber in this embodiment.

The string 30 includes two ends each tied to another end of a relatedone of the limbs 12. The ends of the string 30 are tied to the limbs 12after the limbs 12 are bent. Thus, the string 30 is loaded.

The arrow 40 includes a pile 41, a butt 42, a shaft 43 formed betweenthe pile 41 and the butt 42, fletching 44 attached to the butt 42, astop 45 formed between the butt 42 and the shaft 43, and a nock orrecess 46 defined in the butt 42. The diameter of the pile 41 is largerthan that of the shaft 43. The diameter of the stop 45 is also largerthan that of the shaft 43.

The pile 41 is located in the channel 131, with the buffer 20 locatedbetween the pile 41 and the vent 132. The diameter of the pile 41 issmaller than that of the channel 131 so that the pile 41 is movablewithin the channel 131. The diameter of the pile 41 is larger than thatof the aperture 133 so that the pile 41 cannot be removed from thechannel 131 through the aperture 133.

The butt 42 and the stop 45 are located outside the channel 131, withthe shaft 43 inserted through the aperture 133. The diameter of the stop45 is larger than that of the aperture 133 so that the stop 45 cannot bemoved into the channel 131 through the aperture 133. The diameter of theshaft 43 is smaller than that of the aperture 133, leaving a second gapbetween the shaft 43 and an annular edge within which the aperture 133is defined.

An archer holds the handle 11 with a hand and holds the butt 42 with theother hand. The archer locates a section of the string 30 within thenock 46 beforehand to make sure that the butt 42 is located against thestring 30. The archer pulls the butt 42, thus loading the string 30. Thearcher releases the butt 42 to shoot the arrow 40. The pile 41 moveswithin and along the channel 131 as the arrow 40 flies. As the pile 41moves within the channel 131, some air is expelled from the channel 131via the first gap and the vent 132 while other air is pumped into thechannel 131 through the second gap. The use of the first and second gapsand the vent 132 are important. Otherwise, the pneumatic pressure wouldbuild up in a section of the pipe 13 near the first end, and vacuumwould occur in another section of the pipe 13 near the second end. Suchincrease of the pneumatic pressure and such vacuum would interfere withthe movement of the pile 41 within the channel 131. The pile 41 hits thebuffer 20 just before the stop 45 hits the second end of the pipe 13.The arrow 40 is stopped.

Advantageously, the arrow 40 cannot be detached from the bow 10. Thearrow 40 does not travel for a long distance and cannot but any one.Hence, it does not require a large space to arch with the bow-and-arrowset 100. The archer can train his or her body and mind almost anywhere,at any time.

Referring to FIGS. 5 and 6, there is shown a bow-and-arrow set 300according to a second embodiment of the present invention. The secondembodiment is like the first embodiment except including a front sight60. The front sight 60 can be a mechanical front sight or laser-emittingfront sight. The front sight 60 is useful in helping the archer aim at atarget.

Referring to FIGS. 7 and 8, there is shown a bow-and-arrow set 400according to a third embodiment of the present invention. The thirdembodiment is like the first embodiment except additionally includingcolored rings 72. The colored rings 72 are securely provided around theshaft 43 and evenly located along the shaft 43. An image-identifyingsystem can be used to see the colored rings 72 and count the number ofcolored rings 72 located outside the pipe 13 to tell the value of aforce exerted on the arrow 40. The colored rings 72 can be replaced withcolored annular stripes in another embodiment.

Referring to FIGS. 9 and 10, there is shown a bow-and-arrow set 500according to a fourth embodiment of the present invention. The fourthembodiment is like the first embodiment except additionally including alight 81 and a sensor 82. The light 81 is located on the pipe 13, nearat the first end. The sensor 82 is located within the channel 131, nearthe first end of the pipe 13 and the buffer 20. The light 81 iselectrically connected to the sensor 82. The sensor 82 can be acontact-type or non-contact-type sensor. The sensor 82 is a contact-typesensor such in this embodiment. On contacting the pile 41 moving fromthe buffer 20, the sensor 82 instructs the light 81 to emit red light.On contacting the pile 41 moving towards the buffer 20, the sensor 82actuates the light 81 to emit green light. Thus, the status of the arrow40 can be observed by the archer or any bystanders. The safety isimproved. A piece of electronic equipment can be used to receive thelight and determines the status of the arrow 40.
